rather than unsubstantiated critique, which contributes nothing*, tackle the points point by point starting with Penrose's detailed 'pre-beginning' work.
So you want me to critique your word salad by starting with Roger Penrose? Why would I do that? That doesn't make any sense.
Roger Penrose has a hypothesis with no proof, a mathematical model (with no observation to back it up) regarding the inflation of the early universe. He thinks that he has found evidence, gravitational wave in the CMBR, that show that time and space existed before the big bang and the universe is going through one of many cycles. One central tenet to his theory is that the late state universe will look very similar to the early universe, meaning particles will decay entirely and lose mass. In Penrose's model, the universe is expanding into existing time and space. It's a controversial and unproven model with many things still not matching observed reality.
So, in your first sentence, you went off the rails. There is no evidence that dark matter fuels expansion. In fact, it's gravitationally attractive and holds things together. Dark matter being absorbed? Absorbed where and by what? No one has even actually detected it yet, so saying it get's absorbed and turned into energy is so off base it's not even wrong.
What are you claiming is the void? If you are relying on Penrose, his hypothesis requires time and space already exist. Is that what you are claiming is the void? What do you mean by that? Nothing? Something? What is latent energy? Virtual fluctuations? Do you perhaps mean vacumn energy and virtual particles? Because those ARE actual things, but not the things you describe. What does any of this have to do with Genesis? Why are you jumbling word salad together and claiming it is fact? Why are you taking Sir Roger Penrose's hypothesis and pretending it is fact?
There is your definition of "NOTHING"
Yes, your word salad was exactly that.
